Safety Operation Procedure For Welder
Apr 09, 2018

1. The staff shall be familiar with the welding process of welding machine:

1. Continuous flash welding: continuous flash, top forging, and electric heating on the welder after the top forging;

2. Preheat flash welding: one flash, heat preheating, secondary flash, top forging.

Second, the operators must be familiar with the mechanical and technical performance (such as transformer series, maximum number of welding section, welding, feeding schedule) of the maximum upsetting force,, and the location of the main components and application.

3. Operators shall select welding parameters according to mechanical properties and welding materials.

4. Preparation of welding parts: remove rust, oil and dust from the end of the steel bar 120mm. If the end is bent, it should be straightened or removed.

5. The welding machine should be installed indoors and should have reliable grounding (or zero). The machine should be at least 3 meters apart when the welding machine is installed. And they are connected to different power sources. Each station shall have its own control switch. The switch box to the fuselage wire should be protected. The cross section of a wire shall not be less than the specified sectional area.

6. Check all parts of the welding machine before operation.

1. Whether the mechanical parts such as pressure lever are flexible;

2. Whether various fixtures are firm;

3. Power supply and water supply are normal.

7. Inflammables near the operating site should be cleaned and equipped with fire fighting equipment. The operator must wear protective goggles and gloves and stand on the ground with wooden boards or other insulating materials.

8. The operator must adjust and use the welding current correctly to adapt to the welded steel section. It is strictly forbidden to weld steel bar with diameter.

9. The contact points of the circuit breaker should be cleaned regularly with sandpaper, and the electrode should be filed regularly. All screws of the secondary circuit should be tightened regularly to avoid overheating.

Ten shall not exceed 40 ℃, cooling water temperature, displacement should comply with the specified requirements.

11. The long steel reinforcement should be placed on the bracket when welding. The personnel who cooperate with the rebar at random should pay attention to prevent spark scald. When handling, you should pay attention to the hot stamping.

12. The finished semi-finished products should be stacked neatly.

13. Baffle shall be set in the flash area and no other personnel shall be allowed in when welding.

14. After the welding work is completed in winter, the cooling water in the welding machine should be kept clean so as to avoid the freezing system.
