A pair of of rolling disk electrode replaces the cylindrical electrode of spot welding, performs relative motion with workpiece, to generate the mutual lapping of nugget one by one
Seal-weld welding method.Seam weld is widely used in oil drum, can tank, radiator, aircraft and automotive oil tank, and spray
Gas engine, rocket, in guided missile sealing container thin plate weldering.
The roll welding of automotive oil tank is being welded since general automotive oil tank is top tank and the welding of lower fuel tank steel plate of 1mm or so
It is to move fuel tank with feeling by the hand speed of worker to carry out seam weld when connecing, so welding process is unstable, in roll welding process
In, surface is splashed greatly, and the phosphate coating and zinc coat and other impurity things after welding wheel is welded on fuel tank steel plate can be adhered to rolling
On the idler wheel of welding machine, idler wheel outside diameter and smoothness is caused to have serious deformation, difficulty is caused to the welding of continuous-stable；
In addition (1) is due to being mobile fuel tank, so easily causing welding wheel position deviation, welding wheel is easy to encounter other positions of fuel tank, and initiation is beaten
Fire splashes；Due to the deviation of hand shift position, after completing welding in one week, it will cause weld seam head and the tail and overlap inconsistent, weld joint close
Envelope property does not reach requirement；(2) it due to adhering to other impurities in welding wheel, will cause at the solder joint of part that impression is too deep, lead to weld seam matter
It is poor to measure, or even part occurs and burn, and the weldquality being consequently formed is poor, and fuel tank can not be made to reach the requirement for examining gas pressure test；
(3) due to the material of production fuel tank and fuel tank mold, artificial more expensive up and down is stretched, if phenomena such as burning, product is directly reported
