Why is there such a big difference in the welding quality of these two welds? Is the welding seam so bad that there is no welding slag or something else? Why are there so many lumps?
Did one person do it? Very good
It probably wasn't done by a welder.
Let him polish it off. If it doesn't meet the sample, it won't be accepted: dizzy:
One for machine welding and one for manual welding, right?
They are both hand welded, one is swing welding and the other is paste welding.
One was welded by the master, and the other was practiced by the apprentice while the master was resting. Now that I have practiced, I will also practice polishing. If I'm lucky, I will also practice rework.
There is a problem with the welder’s level. The level in the first picture is not very good either.
