(1)Welding Wire and cutting operations, especially when gas cutting, the use of the jet stream of compressed air or oxygen, so that Mars, molten slag and iron beads flying everywhere (the larger beads and iron slag to molten splash to 5m away from the operating point outside), when the operating environment in the presence of flammable, explosive materials or gases, it may fire and explosion.
(2) welding and cutting operations at high altitude on Mars within reach of inflammable and explosive materials is not clean, workers in the working electrode during the first throw, after the job is not carefully check whether left fire.
(3) welding, gas cutting process according to the specified job requirements place the acetylene generator, before did not seek to check the welding work (cutting) torch, rubber tubing and acetylene generator safety devices.
(4) formulation of the cylinder there is insufficient storage cylinder filling, transport, use and other shortcomings, violations of safety procedures and so on. (5), acetylene, oxygen and other pipeline development, defective installation, use, and not rectification of the deficiencies found in a timely manner.
(6) in the Mig Welding Wires of fuel containers and pipes, did not seek to take appropriate measures. In the implementation of the replacement solder stoppage time, replacement is not complete, in the implementation of replacement with a welding pressure is not enough pressure resulting in added time to import other external fire.

Welding Wire China production from 1995 to 2000, 630,000 tons to 109 tons, of which, solid wires from 6 tons to 110,000 tons; submerged arc welding wire from 2.3 tons to 60,000 tons. Can be seen, welding wire production and growth over a relatively large, so as to promote the semi-automatic? Automatic welding method of promotion. In particular, large or extra large welded structure plant, wire and automated use has reached 78%. In 2000, the amount of
Mig Welding Wires of 109 million tons of finished welded structures 45.9 million tons, accounting for 35% of steel production, welding and steel production output ratio of 0.83%, greater than the proportion of the world's developing countries (0.65% ~ 0.8 %).
