the cause of damage to the side plate of the slags maneuver arm is often damaged after the operation, and there are some damage to the side board of the slagging arm, which is mainly due to the following reasons:
1, the original weld itself has a certain bubble, slag and tiny cracks. when the slagging machine is overloaded, the original weld will produce small cracks which will gradually expand.
2. when welding is not consistent with the performance of the welding rod and plate, causing certain cracks.
3. because of the larger size of the moving arm, it is difficult to use reliable and effective heating and thermal insulation measures. after welding, the hardened zone of the weld metal is not completely removed, which leads to the decrease of the weld strength.
4. during the operation of slag scraper, due to the larger vibration impact, the uneven weld seam leads to weld cracking.
the above is the reason for the damage of the side plate of the scraper mobile arm, hoping to provide some help in the daily maintenance work of the slag scraper.
