8) back of weld of pure aluminum material is subjected to immediately when, the pre-heat treatment reaches pre-heat effect, welded
While welding position is heated using manual grilled gun, heating-up temperature be 250~350 DEG C；
9), welding continues to be heat-treated after carrying out pure aluminum material using manual grilled gun after terminating, rear heat treatment duration
For 4~6min, until whole welding procedure is completed.
Preferably, welded in welding using metal argon arc welding, the argon concentration is 99.9% or 99.99%.
Preferably, the typical thickness of pure aluminum material is 12~30mm.
Preferably, in step 3) to step 5) and step 7) to step 9), preheated, welded using manual grilled gun
When heating, being heat-treated afterwards, three needs uninterruptedly to carry out according to preheating, heating, rear hot order.
Preferably, in welding, it is necessary to quick and keep continual and be subjected to.
Preferably, typical speed of welding during welding is 60~80cm/min.
Preferably, typical welding current during welding is 300~400A.
Using above-mentioned technical proposal, the present invention compared with prior art, has the advantages that：1), back chipping efficiency high,
It is disposable whole in back chipping and to keep continuously completing back chipping on earth, improve back chipping efficiency；2), pre-
Welded immediately after thermojunction beam, and the continual heating in welding, continual rear heat treatment is also carried out after welding,
Welded seam area can be quickly returning to by avoiding the vapor in air, and substantial amounts of hydrogen blistering stays in weldering caused by meeting when avoiding welding
In seam, welding quality is improved.
