Description
Technical field
The present invention is a kind of multi-convex point pole electric resistance welding projection welding method of T-type connection for cable ladder production, is belonged to
Resistance projection-welding connection technology field.
Background technique
It is all arc welding or gas that the crosspiece of cable ladder, which connects the assembled welding fabrication technique used with the T-type of side plate, at present
Body protection weldering makes to fill silk and melts welding by pulse short circuit, and since cable ladder is using thin plate, this welding manner is frequent
There is the unstable phenomenon of the starting the arc, is easy to produce solder skip or burn-through, makes a big impact to the continuity and reliability of welding, and
And gas shielded arc welding is heat molten type welding, low efficiency, energy consumption are big, and workpiece deflection is big, and precision does not reach requirement, at plate-side plate welding
Outside toward contact can generate hole and overheat caused by welding trace, especially material selection have antiseptic property hot-dip galvanizing sheet steel
When with stainless-steel sheet, mistakes thermal response when arc-welding or gas shielded arc welding are because of welding will cause weld and aoxidize, to weld
Antiseptic property damages, and influences the quality and overall appearance of product, it is necessary to reach antiseptic property and outer by surface treatment again
The requirement of consistency is seen, and is surface-treated and not only will increase product cost, and is inevitably right in surface treatment process
Environmental effects, or even pollute.
