Regarding the problem of choose equipment, surface clearing, groove type and mismatch of the size and technique treatment in the repairing of rear axle housing in mining truck, the solution of low hydrogen sodium alkaline electrode and dc arc welding inverter was put forward. After test by customer, there no problem accuring in the running of 30 000 km, and the maintenance cost was saved.
