Welding method for obtaining uniform height of bead
专利汇可以提供Welding method for obtaining uniform height of bead专利检索，专利查询，专利分析的服务。并且PURPOSE: To reduce the cost and to improve the quality of weld zone, without carrying out the complicated control of the conventional method, by comparing the detecting signal, for the distance between the surface of parent metal and the torch, with the reference signal, and by varying the welding speed and the flow rate of shielding gas.
CONSTITUTION: This method is constituted of the conventional stick out controlling mechanism being added with the following block diagram. The height H
2 from the surface L
1 of the parent metal 20 to the distance detector 12 (or the torch 1) is detected by this detector 12, and is converted into voltage by the voltage converter 13; this voltage signal and the voltage signal from the voltage generator 15 for the reference distance, are compared by the comparator 14; the resulted difference signal is transmitted to the controller 16 for the welding work condition; this controller 16 controls the welding speed and the flow rate of the shielding gas respectively through the welding propelling portion 18 and the gas shielding portion 17; and when the torch 1 is to collide with the parent metal surface L
1 , the torch 1 is stopped through the emergency stop portion 19. As a result, the height of beads becomes constant, the complicated control of the conventional method becomes unnecessary, and the cost is reduced.
