【Abstract】 The welding torch of carbon-electrode arc constrained by argon is made for bead welding of WC grain in order to decrease the burning and depositing of hard metal alloys. The result shows that the burning and depositing of hard metal alloys can be.decreased obviously in bead welding of WC grain by this welding torch.更多还原
