As a large crushing equipment, the quality of jaw crusher is one of the most concern for the user, therefore, manufacturers can not ignore the details of main components in manufacturing, disadvantages of jaw crusher including welding parts, in order to achieve the best welding effect, operators need to understand the attention of jaw crusher parts welding:

1）select the position of welding. Welding method is the most commonly used vibration welding method, the welding should first consider the most effective welding position, welding minimum maximum effectiveness.

2）consider the welding is convenient operation. General to ensure proper angle between minimum and operation when the electrode welding operations, if the structure is special, unable to meet this requirement, the red star industry by bending measures such as welding electrode.

3）The position of the rational arrangement of welding. The mutual position of reasonable arrangement of components before welding, welding parts to ensure the rigidity. In some particularly important welding parts, the thickness of the steel plate in different welding, must make the two center line, to avoid bending moment.

4）use less or no groove. Maximum board manual electric arc welding without groove of one-sided welding thick, 4 mm to 6 mm, bilateral welding. The general slope angle is 60 ~ 90 degrees, darker than crack depth of 2 ~ 3 mm, the bottom should shovel into the semicircular, should double shovel into the "X" type groove penetrated crack.

5）weld metal crack the best suitable hole drilled the first. In the weld metal crack extension, to prevent cracks, should be pre cracks in the terminal and the beginning end drill one to two circular hole diameter and thickness of the weld metal to adapt, and the cracks in welding all is over, then the welding die.
