美国某公司研究成功了一种水冷却的手工电弧焊接法(简称LC法),对同样直径的焊条可以大大增高最大容许焊接电流,这是利用夹在特种手把中的焊条上端通过电流时发出的热量而达到的。 LC焊接法的原理如图所示。沿着手把沟槽通入2.1公斤/公分~2压力的循环水流作为冷却介质。增高最大容许焊接电流,可以使熔敷速度提高到4.5～12.7公斤/小时。LC法用直径6.35公厘的焊条焊接;也允许用直径7.9和9.5公厘的焊
A company in the United States has successfully researched a water-cooled manual arc welding method (referred to as LC method), which greatly increases the maximum allowable welding current for electrodes with the same diameter. This is achieved when the upper end of an electrode clamped in a special handle passes through an electric current The heat is reached. The principle of LC welding method is shown in the figure. Along the handle channel access 2.1 kg / cm ~ 2 pressure circulating water as a cooling medium. Increase the maximum allowable welding current, the deposition rate can be increased to 4.5 ~ 12.7 kg / h. LC method with a diameter of 6.35 mm welding electrodes; also allows the use of 7.9 and 9.5 mm diameter welding
