Can you weld if the engine base of the forklift is cracked?

The forklift engine base can be welded if it is broken, and it can be welded with two welding processes: hot welding and cold welding.

Thermal welding: J506 electrode is selected, and the fracture is beveled to ensure welding penetration under the premise of preheating the fracture at about 550 degrees, and the cooling is slow after welding, so as to reduce the shrinkage stress cracks generated during cooling.

Cold welding: The wewelding777 high crack resistant cast iron electrode is selected, and the groove depth can be guaranteed under the premise that the groove depth can ensure the depth of the groove 2 3, and the cold welding process is used to keep the temperature of the parent body not rising during the welding process.

Wewelding777 Tips for Using Processes.

1. It is necessary to do proper surface cleaning before welding, and the welded joint should be obliquely cut into a U-shaped groove.

2. Crack holes at both ends of the crack to prevent the expansion of the crack during the welding process.

3. When the repair angle is not good, you can choose the wewelding100 electrode cold slotting to form an effective U-shaped or V-shaped groove.

4. Weld with as little current as possible, medium arc length, and slightly inclined to the welding direction.

5. It is recommended that the weld bead should be short, thin and narrow transversely oscillating torch to fill the weld before stopping the arc welding, usually without heat treatment, allowing the parts to cool slowly.

No, you must change the base.

1.When the start switch is turned on, the starter spins at high speed and the engine crankshaft does not respond. This phenomenon indicates that the fault occurred on the transmission mechanism of the starter, which may be caused by the wear of the transmission gear or the one-way clutch operator's pants.

2.The starter does not work properly, and the drive gear does not turn. There are many reasons for this, such as problems with the pure code line of the power supply, ablation of the contact disc of the starter switch, and excessive engine resistance.

3.The starter has insufficient power output to drive the crankshaft. A short circuit in the excitation coil and a loss of power in the battery can cause a lack of power in the starter.

4.The starter is running with a harsh sound. This can be caused by a one-way clutch jam or improper installation of the starter.

5.There is a "click" sound when the starter is switched, but it does not work. This phenomenon can be caused by a broken coil or a severe loss of power in the battery.

After the starter of the forklift is broken, it only needs to be repaired, and there is no other version.

The forklift crane is broken, of course, it is to find after-sales service to repair. Watching them repair can also give you an idea of how to repair and maintain.
