THE 3 BROTHERS IN OIL & GAS — WHO HAS HARDER JOB?

A. WELDER — The Maker (Hands work)
- Physical hardest. Heat, smoke, sparks, kneeling inside pipe, 6G overhead burning neck.
- Must control hands steady for 3 hours. One mistake = cut and re-weld whole joint.
- Body suffers — eyes, back, lungs. Skill is in your hands.

B. NDT INSPECTOR — The Detective (Eyes of machine)
- Mental + Technical hardest. Uses UT, RT, MT, PT machines to find defects EYE cannot see — crack inside weld 2mm.
- Must know welding + physics + codes (ASME, API). If he misses defect, pipe explodes, people die.
- Job is lonely and pressure — he must FAIL his own friend welder's job. No friendship in NDT.

C. QA/QC — The Judge (Paper + Responsibility)
- Responsibility hardest. He signs paper that says "This weld is good for 30 years in oil rig".
- Must know WPS, PQR, codes, documentation, manages Welders + NDT. If anything fails, QA/QC goes to court, not welder.
- Fights with everybody — production says "approve fast", he says "no, redo".

7 TYPES OF CALIPERS

The precision measuring tools.

1. VERNIER CALIPER — The old school master tool. Has main scale + small vernier scale. Measures to 0.02mm. No battery, lasts forever. Every good fabricator must know how to read it.

2. DIGITAL CALIPER — Modern version. Shows reading on screen like 20.25mm. Easy, fast, no calculation. Uses battery. Most used now for thickness, diameter.

3. DIAL CALIPER — Has clock face with needle. Needle shows 0.01mm. Better than vernier, no battery like digital. Good for workshop with dust.

_These 3 do same job — Outside, Inside, Depth — 3-in-1 tool. Use for: outside of pipe, inside of hole, depth of groove._

4. OUTSIDE CALIPER — The X-shaped like scissors with curved ends outward. Only for outside diameter of pipe, bar, thickness. You measure with it, then check size on ruler.

5. INSIDE CALIPER — Same but small feet pointing out. Only for inside — hole diameter, inside of pipe, groove width.

6. DEPTH CALIPER — Has T-base. Only for depth — how deep is hole, step, groove.

7. ODD LEG CALIPER / JENNY CALIPER — One leg straight, one leg bent. For marking — scribing line parallel to edge, finding center of round bar. Very important for fabrication layout.

Using wrong disc breaks machine and injures.

1. CUT-OFF DISC — Thin black disc. ONLY for cutting iron rods, pipes, sheets. Cut straight 90°. Never use side to grind — it will burst.

2. FLAP DISC — Sandpaper flaps. For grinding welds smooth + polishing same time. Your best friend for finishing gates.

3. DEPRESSED CENTER DISC — Thick with center down. For heavy grinding of thick welds, removing excess metal.

4. CUP GRINDING DISC — Metal cup with segments. For concrete floor grinding, not for steel.

5. DIAMOND CUTTING DISC — Silver with segments. For tiles, concrete, stone. Not for iron.

6. STRIPPING DISC — Black open sponge. For removing paint, rust, without cutting metal. Best for old gate repainting.

7. FIBER DISC — Red rough fiber. For heavy rust and paint removal on steel, faster than wire brush.

8. SILICON CARBIDE DISC — Green label, thin. For stainless steel and stone, does not overheat stainless.

9. ZIRCONIA FLAP DISC — Blue flaps. Stronger than normal flap disc — for heavy stainless and thick welds.

10. DIAMOND CUP DISC — Like cup but diamond edge. For grinding concrete, terrazzo.

11. GRINDING WHEEL — Thick grey wheel. For bench grinder machine, sharpening tools, chisels.

12. FELT POLISHING DISC — White soft wool. Final polish with compound to make stainless shine like mirror.

WELDING POSITIONS (G = Groove)

PLATE:
- 1G (Flat): Weld on flat table top — easiest, gravity helps you.
- 2G (Horizontal): Weld on vertical plate, you move left/right — like welding a gate standing.
- 3G (Vertical): Weld up from bottom to top on vertical plate — difficult, needs low heat.
- 4G (Overhead): Weld under a plate above your head — hardest, sparks fall on you.

PIPE:
- PIPE 1G Rotating: Pipe turns, you weld flat on top — easiest pipe weld.
- PIPE 2G Fixed: Pipe standing vertical, you weld around horizontally.
- PIPE 5G Fixed: Pipe horizontal fixed, you weld around it changing from flat to overhead.
- PIPE 6G Inclined: Pipe fixed at 45°, you weld all positions at once — the master test for any welder.
- PIPE 6GR Restricted: Same as 6G but with a ring blocking you — most difficult, for 6G certification.

Using wrong bit is why bits break and holes become crooked.

1. TWIST DRILL BIT (General Purpose)
Your everyday bit. For mild steel, galvanized, stainless (small sizes). This is what you use 90% for gates, burglar proof. Always use center punch first.

2. CENTER DRILL BIT
Very short, strong tip. Used to make a small starting hole so the main drill does not walk/slide. Professional work = always start with this.

3. COBALT DRILL BIT (Gold color)
Special for HARD materials — hardened steel, stainless steel, thick plates. Has 5-8% cobalt inside, doesn't lose sharpness when hot. For Whitestar stainless gates, THIS is the one to buy, not normal black bit.

4. MASONRY DRILL BIT (Arrow head)
With carbide tip at front. ONLY for concrete, blocks, bricks, tiles. When you want to fix your gates/carport to wall. NEVER use on metal, it will spoil instantly.

5. STEP DRILL BIT (Christmas tree)
One bit drills many sizes — 4mm, 6mm, 8mm... up to 20mm. Best for thin sheet metal, like making holes in light gauge for electrical boxes, thin burglar proof. Gives clean hole, no burr.

6. SPADE DRILL BIT (Flat with 25)
For WOOD only. For wooden doors, ceiling work. Flat paddle shape cuts wood fast. Don't use on metal.

7. HOLE SAW BIT
For VERY big holes — 30mm to 150mm. Like for lock holes on gates, passing pipes. Has teeth like a cup. You need slow speed + oil.

8. COUNTERSINK BIT
Not for drilling hole — for making top of hole conical (V-shape) so that screw head sits flat inside metal. Important for neat finishing work on stainless.

9. REAMER BIT
Not really a drill — it's for making an existing hole PERFECT round and exact size. After you drill 13.8mm, reamer makes it exactly 14mm smooth. For precision hinges.

10. CARBIDE TIPPED DRILL BIT
Strongest. Tip has tungsten carbide. For extremely hard steel, tiles, and where normal bit fails. Expensive — don't drop it, tip will crack.

WHAT IS A FILE?
A steel tool with sharp teeth for cutting, smoothing, and shaping metal after cutting or welding.

- Flat File: The master. Flat on both sides. For general filing of flat surfaces, removing burrs after cutting. You will use this 80% of the time.

- Half-Round File: One side flat, one side curved. For flat surfaces AND inside curves of gates, pipes. Very useful for White Star jobs.

- Round File / Rat-Tail: Fully round. For enlarging round holes, filing inside pipes, curves of burglar proof.

- Square File: Square shape. For square holes, slots, keyways. Makes corners sharp 90 degrees.

- Triangular File: Triangle shape — also called Three-Square File. For filing V-grooves, sharpening saw teeth, cleaning inside corners

This picture shows 12 types of wire brushes, but they fall into 2 families:

FAMILY 1: HAND BRUSHES (Manual Cleaning)
For cleaning BEFORE and AFTER welding:

- HAND WIRE BRUSH / PLASTIC HANDLE WIRE BRUSH:
Your daily tool. To remove slag, rust, dirt. Plastic handle lasts longer in oil. Every intern must have one in his toolbox.

- SCRATCH WIRE BRUSH / STRIP WIRE BRUSH: Long wooden handle, brass or steel bristles. For light cleaning of stainless, not scratching base metal too much. Use for aluminium work at White Star — brass doesn't contaminate.

- TUBE WIRE BRUSH / BOTTLE WIRE BRUSH: Long twist with loop. For INSIDE pipes, square tubes, bore holes. After you cut square tube, you use this to clean inside rust before welding. Very important for 2.0mm - 6.0mm tubes we use.

FAMILY 2: POWER BRUSHES (For Grinder/Drill)
WARNING: PPE - Goggles, gloves, no loose clothes. These throw wires!

- WIRE WHEEL BRUSH / DISC WIRE BRUSH: Flat wheel for angle grinder. For large flat surfaces — cleaning rust off plates, gates, frames fast.

- KNOT WIRE BRUSH: Twisted knots, very aggressive. For heavy rust, heavy slag, weld spatter removal. Use when 6013 or 7018 leaves hard slag.

- CRIMPED WIRE BRUSH: Wavy wires, soft. For light rust, paint removal, polishing. Won't gouge metal. Good for final finishing before painting your gates.

- CUP WIRE BRUSH: Cup shape with threaded nut. Best for angle grinder. For flat surfaces and corners — cleans big area quickly. Red top one is for grinder M14 thread.

- END WIRE BRUSH: Small pencil type with shank. For drill machine. For tight spots — inside corners of T-Joint, Corner Joint where cup cannot reach.
