Background
At present, safety accidents frequently occur in the international petroleum industry, such as serious ecological balance problems caused by oil leakage accidents in Mexico and the like. The reason is mainly due to the quality problem of the oil blowout preventer, and the oil leakage caused by the fact that the oil pipeline is not blocked by the blowout preventer in time when the blowout phenomenon occurs cannot be controlled. The emergency blocking of the piston and the piston connecting rod of the blowout preventer plays a key role when oil leakage occurs. At present, the soft base wear-resistant material on the market is transferred to a piston and a piston connecting rod through various forms, flame brazing, pulse arc welding and the like are mainly found according to investigation, most of the materials are mainly manual, and the following problems are easily caused in the construction process:

The higher peak current of the pulse when the conventional pulse MIG welding is adopted causes the overhigh iron content in the welding seam of the aluminum bronze, and the higher the iron content when the piston and the piston connecting rod are used, the larger the influence of the electric spark generated is.
2. The welding efficiency is low, the temperature of a workpiece is often increased to be very high during the conventional pulse MIG welding, and the interlayer temperature needs to be waited during the multi-layer and multi-pass welding. An AC power supply is needed during TIG welding, and the efficiency is affected by frequent replacement of a tungsten needle and labor intensity of personnel during welding.
3. The safety coefficient is low, the flame is oxyacetylene during flame welding, tempering is easy to generate, and the safety coefficient of an operator is low.
4. The operation environment is severe, flame is oxyacetylene during spray welding, the ambient temperature is above 40 ℃ during operation of personnel in summer, and occupational health cannot be guaranteed.
5. The process difficulty is higher, the dependence of personnel on the process or the experience requirement of an operator is strict during conventional pulse welding or TIG welding, in addition, the adjustment of the duration and degree of heating of the operator during flame brazing needs very rich experience, and serious quality problems can be caused if a certain point is ignored.
