Stick welding is also known as Shield metal arc welding (SMAW). This method of arc welding uses the heat of the arc between the coated rod and the tank. The commonly used method with protection from the decomposition of the solder sheath when burned during welding, in this method is not using pressure, and the filling metal obtained from the welding rod.
Advantages and areas of utilization
SMAW welding or arc welding is one of the most popular welding methods.
Welding rods can be welded to a wide range of metals in all welding positions from the smallest thickness to the largest thicknesses.
Self-sticking sheaths provide a welding environment for the welding process.
Less wind damage than welding processes with gas protection.
The investment in equipment is relatively inexpensive, simple and highly mobile.
This method is used in fabrication and in mining work for construction and maintenance.
Limitations of welding method
The major limitation of the cored arc welding method is discontinuous (discontinuous).
Low welding efficiency due to stop to replace the welding rod.
Waste welding materials.
The slag should be removed from the welding line after welding.
Coating of welding rod
Gases from the decomposition of certain components in the coating to protect the arc from the air.
· Deoxidizing agent for pushing air and purifying the metal.
Slag from the fire of the sheath serves to protect the solder from deposition of air.
· The ionization factor creates the most stable arc and works with alternating current.
Special alloying elements, characteristic for deposition of metal welds.
Iron powder improves the performance of the welding rod.
