石油石化装备现场再制造是在装备、装置所在地,在现场进行石油石化装备的恢复及升级,它是一种基于资源循环利用的装备制造新模式,免除或大幅度降低了装备拆除、再安装、吊装以及往返运输的费用,获得了节能、节材、减排效果,创造了巨大的经济效益,是一个长期稳定并不断发展的市场。类激光高能脉冲精密冷补技术是一种新型冷补工艺,其能量集中、作用时间短、修复速度快、热影响区小、具有原位热处理效果等特点,该技术是在氩气氛围下,利用断续高能脉冲电流在电极和工件之间形成的瞬间电弧,使补材和工件瞬时熔结,形成冶金结合,具有较小热影响区。电弧的产生由起弧、维弧、
Petroleum and petrochemical equipment on-site remanufacturing is in the equipment, equipment location, on-site petrochemical equipment recovery and upgrading, it is a resource-based recycling equipment manufacturing a new model, eliminating or substantially reducing equipment removal, re-installation, Lifting and transportation costs, access to energy-saving, materials, emission reduction effect, creating enormous economic benefits, is a long-term stable and continuous development of the market. The high-energy laser pulse laser technology is a new type of cold-fill technology, which has the characteristics of concentrated energy, short acting time, fast repair speed, small heat-affected zone and in-situ heat treatment effect. Under argon atmosphere, The use of intermittent high-energy pulse current in the electrode and the workpiece formed between the instantaneous arc, so that complementary materials and the workpiece instantaneous sintering, the formation of metallurgical bonding, with a smaller heat-affected zone. Arc generated by the arc, the arc,
