Welding process precautions:
1, the selection of argon arc welding process parameters (including current, gas flow, tungsten electrode extension length, etc.) should be based on the type of workpiece material, thickness, joint form, welding position and their own actual situation after comprehensive consideration.
2, before welding to clean the surface of the workpiece oil, water and other impurities, so as not to affect the quality of welding.
3, under normal circumstances, when the current is 100A~200A, the gas flow rate is appropriate in 9~14L/min; When 200A~300A, the gas flow rate of 14~18L/min is appropriate; Tungsten electrode extension length is 3~5mm, arc length is 1~3mm; When the wind speed is ≥1.0m/s, windproof measures should be taken in time. Argon gas protection is recommended at the back of the welding area.
4, the size of the welding line energy directly affects the mechanical properties of the weld, the user should be timely adjusted according to the actual situation.
5, the above suggestions are for reference only, the user should be based on their own actual situation before use process assessment.
Welding wire handling and storage:
1, simple argon arc welding wire in the handling, should be handled lightly, to avoid damaging the plastic packaging and deformation of the welding wire, affecting the use of.
2, argon arc welding wire afraid of water, not close to fire, not high temperature, should pay special attention to storage.
3. When a cylinder of welding wire is not used up and needs to be stored, the plastic cylinder should be sealed in time to prevent rust.
4, warehouse storage, the distance from the wall should be greater than 30cm is appropriate, should be placed clearly according to specifications, models, to prevent mixing, and according to the principle of "first in first out" reasonable use.
