Welding Tips and Tricks

Is the any benefit structurally from varying the type of weave you do? I've had some people say to walk forward on both up and down stroke and some say only walk forward on one and then roll straight across the other. The argument for that was to ensure there is enough metal being laid in the middle of the weld as the sides. All I've noticed is a tighter weave which I'm not all that concerned about. I have a pretty tight weave anyways, depending on how early in the morning it is.

I would guess that if the welds were of equal thickness, with identical filler, and had no undercut or other deformities with all other variables the same except the weave pattern. Any differance would only be detectable at a lab testing level during destructive testing. Or am I crazy?

A weave pattern that allows large areas of the underlying metal to be untouched by the arc can result in areas of non-fusion. Keep em tight.

Another consideration is the added heat input from the slower travel speeds however this relates regardless of the pattern used and is more of a concern for welds in which toughness/impact strength is a concern.

Have a great day.

That's kinda what I was thinking. I can lay it down to whatever degree they want. Doesn't matter to me. Different strokes for different folks I guess.
