Weld finishing with oxy-cut
Weld finishing with oxy-cut
(OP)
Hi All,
I am working on a project and yesterday I noticed something that did not look familiar to me.
We are talking about structural steel (grade 300 / 350). One of the welder was finishing the weld profile wth oxy-cut flame.
It was the first time I have witnessed a similar situation. Is it normal or acceptable practice ? I would suppose that later on grinder will be used anyway to improve the finishing, but in terms of adding another termal cycle to the joint.. wouldn't it be a bit detrimental?
Thanks all!

Oxy-fuel gouging and carbon arc gouging is often used to remove weld defects in preparation for repair. I see little difference in what the welder is currently doing and preparing a defective weld.

Al brings up a good point based on an assumption. I may have a translation issue with how you refer to weld profile. Are we talking about removal of excessive weld reinforcement or preparation to repair a finished weld that contains a defect?
If so, I agree with above. Regarding weld profile or smoothing a rough weld face, I see no reason to use an oxy-acetylene torch, a grinder works best.

My (very) bad. gatw assumption is correct: the welder was removing excessive weld face reinforcement using a oxy-fuel torch., not as preparation for a repair (in that case they generally adopt carbon-arc gouging).
(As partial excuse, English is not my first language.. OT: do you have a link with technical jargon specific to welding?)
RE: Weld finishing with oxy-cut
The use of nonstandard terms only muddies the water because there is no comprehensive document that helps define the "slang" terminology. This is particularly troublesome when the audience is international.

Much appreciated as always!

Not sure what your role actually is but you should be reporting it to someone higher up the food chain as it is totally unprofessional work (as noted by Al & metengr).
A competent welder makes his/her weld and then walks away.
A less competent welder makes his/her weld and then dresses it to make it look good with a grinder.
