The process of gas welding pipeline:
Preparation:
Clean the surface of the pipe to be welded to remove dirt, rust and other contaminants that may affect the quality of the weld.
Make sure the plumbing is installed correctly. Joint construction shall be suitable for gas welding.
install equipment:
Gas welding requires a torch that mixes fuel gas and oxygen and provides a controlled flame.
Appropriate gas regulators are used to control the flow of fuel gas and oxygen.
Choose the size of the torch tip according to the thickness of the pipe and the desired welding conditions.
Light the flame:
Open the valves of the fuel and oxygen cylinders.
Light the flame on the torch tip with a lighter.
To adjust the flame:
A neutral flame with a balanced mixture of fuel gas and oxygen is an ideal welding flame. This flame has a distinct inner cone, a wider middle cone and a weaker outer cone.
The heat intensity of the flame is adjusted by varying the ratio of oxygen to fuel gas and the distance of the torch tip from the workpiece.
Start welding:
Heat the edges of the pipe to be welded with a neutral flame until the proper melting temperature is reached.
Filler metal is added to the molten pool to form the weld.
Welding process:
Move the torch along the joint while maintaining the proper flame and heat to melt the base metal and filler metal.
Controls the movement of filler metal rods to ensure proper fusion.
Cool and check:
Allow the weld to cool gradually.
After the weld has cooled sufficiently, inspect the weld for fusion, penetration and any defects.
