Embodiment Construction
[0010] According to the specifications of the air duct, it is preferred to divide the stainless steel plate with a width of 1250mm into two pieces for cutting. According to the flanging size of 15mm, first fold the required flanging of the horizontal welding part of the air duct on the folding machine; the air duct reinforcement frame is used The stainless steel angle steel is welded by electric welding according to the specification and size of the air duct.
[0011] Assemble the two stainless steel plates after laying the material, put the reinforced frame that has been made on the assembled air duct before welding, fix it with clamps, and perform longitudinal welding of the air duct in the form of fillet welding , in order to heat and cool the weld seam of the air pipe evenly and reduce deformation, welding is performed in reverse from the middle to both ends during welding; when assembling, spot weld the air pipe first, fix it with a clamp before welding, welding The high ...
