What is the ideal height of weld bead?

When comes to a good weld the height of bead should be?

The height of the weld bead should be approximately 1/32″–3/64″ (0.8 mm–1.2 mm). As the weld bead reaches the correct width, the welder moves the electrode forward at a constant speed. A weave bead is one made along a line while the electrode is moved from side to side.

How are weld beads measured?

Although the two measured parameters (width and height) were obtained from different approaches, the image processing methodology in both cases comprises the following image processing routines: image enhancement; image thresholding; labeling; and reference point location.

What will happen if the current is too high to a weld bead?

If the amperage is set too high, it will give you a bead that is wide, flat and irregular, and it’s very easy to end up with excess spatter. With all other things being equal, voltage determines the profile of the weld bead.

Can you weld over a bad weld?

Sure you can weld over an existing weld. Unless you can’t weld to begin with because then you may struggle. Another hindrance would be if you forgot to pay the electric bill or if you didn’t have a proper ground.

Why are my welds so tall?

Your mig bead being too tall indicates that you have not set enough voltage to enable the arc pool to melt the incoming wire. You can either reduce your wire feed (which will reduce your amp input ) or alternately increase your voltage setting.

What is 2F and 3G means?

2 refers to a horizontal position – either 2F or 2G. 3 is a vertical position – either 3F or 3G. 4 is an overhead position – either 4F or 4G.

Why you should not wear nylon clothing when welding?

Never wear nylon or polyester while welding. If they catch fire you can be burned very badly. Nomex is the best because it won’t burn, but it’s expensive. It will still get holes in it from the sparks but it won’t support a flame.
