Arc Welding Hints—Weaving

1URING welding it is necessary at / times to deposit a wider .bead than n be obtained from a straight run, and erefore it is the practice to oscillate or ;.ave the electrode at right angles to the rection -of the welding. The normal dth of this oscillation is roughly four five Vanes the width of the electrode, A to obtain even deposits and neat )rk, easy and regular movement is sential. In order to avoid undercut at a side of the weave, the welder should )vu down on reaching each side; this aans a pause at the end of the circular overnent, and a speeding up across to a opposite side.

Several types of weave are in use, and start the beginner off with the popular Le, study Fig_ 1, which is a simple half'cular movement. The appearance of the deposit will be heavier, but it should be neat and regular. This technique is just as important for the garage welder as any other, and will play a part in

heavy padding. Fig. 2 shows the reverse method to Fig.. 1 and again is halfcircular. Fig. 3 shows the zig-zag, and Fig. 4 the continuous S. All methods should be practised, as all can play a part in good welding.
