5083 aluminum plate can be welded aluminum, but because it is relatively fragile, so in the welding time may occur cracks, then how to prevent 5083 aluminum plate in the welding process cracks?The following 5083 aluminum plate manufacturers to a measure.

1, first of all, in order to reduce the tendency of weld crack, choose a high crack resistance electrode.

2, the second two pieces of different thickness of 5083 aluminum plate splicing, in order to make the welding seam can smooth transition, must be in the thick plate groove.

3, and then the preheating: for 5083 aluminum plate, before welding, to preheat, the joint structure of each side of the heating width shall not be less than 5 times of the plate thickness, preheating area is set as the groove on both sides of the range of 75~100mm, preheating temperature is 200~350℃.

4, in welding, the two pieces of 5083 aluminum plate flat on the workbench, maintain a gap of 1mm, and welding fixture will press the workpiece on the platform, immediately after preheating positioning welding, so as to make the 5083 aluminum plate through welding.

5. Short pass welding should be used to make each section of the weld to be welded repeatedly heated in a short time.5083 aluminum plate welding, the use of short jump welding method, the length of each weld is 150~200mm, can make the weld and heat affected zone slow cooling, reduce the tendency to crack

To prevent cracks in the welding process of 5083 aluminum plate, this is it. If you want to know the price of 5083 aluminum plate, you can consult us.
