Electric transfer wagon frame belongs to metal arc welder, welding deformation is difficult to avoid, but can be controlled, good welding process can control the welding deformation to minimum state.

 

In order to better control the welding deformation of electric transfer wagon frame, it is suggested that in welding, the following aspects should be paid attention to:

 

1) reasonable welding rod and welding current should be selected for the thickness of different plates and the size of welds. This problem is familiar to ordinary welders.

 

2) for the longer continuous weld, it is not necessary to go through one seam at a time.After welding, stop and weld the other part. After cooling, then welding.

 

3) for a large area of weld, absolutely not a row of weld after welding, and then with just welding, the welding seam of adjacent weld is still spot welding, first to locate and fixed, diagonal welding again.

 

4) there are both flat seam and under the condition of vertical weld, welding position and fixed first commonly, and welding seam, the seam welding flat (specific welding, according to the actual situation of the scene, there is only one purpose, to reduce welding deformation).

 

In conclusion, there are many methods and measures to avoid welding deformation of electric transfer wagon frame. In actual welding process, the welding deformation quantity should be controlled to the minimum value.
