BAD Welder - Watch the CRACK in the Root Run - C pinned comment.

This WELDOR is producing a DANGEROUS welding REPAIR.

I get the feeling that this is a HIGHER and HARDER carbon / alloy steel.

He has NOT removed the sleeve inside the housing.

The part to be welded, has not been ground out, to the ROOT of the crack.to a gap of say 2 to 3mm.


This part needs pre-heating - with a blow torch - up to say 250 - 300*C.


It cools too fast.

When the HARDER alloy steel shrinks after the weld is placed, it cracks up, from the weld root, AROUND the sleeve, into the weld.

The subsequent passes - the slag (spent flux) feeds into the crack and builds a wall of slag up into the center of the weld.

The giant slag inclusion sort of effectively "removes" sort of almost 2/3 of the weld joining the parts.

AND the capping runs cover OVER the slag inclusion and crack in the weld root.

So on the surface - it LOOKS like a good weld, it is in fact a deadly dangerous weld.

It has a cracked root - this is a BAD stress concentrator.

2/3rds of the weld is a slag inclusion.

This fucktard of a welder is going to get other people injured or killed or create catastrophic failure.

This is the difference between a professional and an idiot.

The sleeve should have been removed, the crack that should have been fully ground out, the part should have been preheated, and a FULL penetration run, that welds through to the other side AND it takes, in both sides of the root.

Then the penetrated weld, should have been ground back to metal, from the inside of the hole, and the root run should have been ground out until it's nice and clean, and then the subsequent passes made and a clean out, a light grind, and the remaining passes and light grinds between them.
