Fwd: [MW:14105] Re: Regarding Electrode Weaving

As your weaving width increases there will be maximum chances of slag entrapment at both sides (left & right) because of prior solidification of weld before welding of respective edges. Your weld pool should be in fused state during weaving to avoid slag entrapment.

Hi,

As per Code it is a Non essential variable and Code doesn't specify the weave bead width limits. But you have to specify on the WPS (Stringe/Weave bead). Its a good engineering practice to limit the weave bead width to control the heat input.

Respected Experts,


We generally mention in WPS/PQR weaving of Electrode should be three times the Electrode dia...I have query is Code restrict for this ,anywhere written in code aur it is on general experience...


Thanks & Regards
