Pupil differences increase non-ferrous metals.

Tungsten inert gas welding or called gas tungsten arc welding is a kind of non-melting tungsten electrode welding arc welding method.

TIG welding is often referred to as TIG welding is a non-consumable electrode and the work piece between the heat-generating arc welding, the electrode rod, molten pool, the arc and working materials are made near the heated zone gaseous state this protection is protection from the atmosphere is mixed into the gas or gas mixture supply is usually an inert gas stream must be able to provide full protection because even a very small amount of air mixed also contaminate the weld.

After power on, through the current heating tungsten wire, tungsten is heating wire.

Tungsten electrode grinding machine for its precise and angle of taper longitudinal grinding to make tungsten maintain optimal dimensions.

The utility model relates to a pair of metal wire coated billet welding equipment to quickly replace tungsten rod devices.

Gan small boxes bromine tungsten lamp light movie projector actual screenings and method of operation.

Tungsten steel watches with high hardness, wear resistance, strength and toughness, heat resistance, corrosion resistance and a series of excellent properties, especially its high hardness and wear resistance even at 500 ℃ temperature also remained unchanged in 1000 ℃ is still very high hardness, good gloss, metallic feeling strong, so tungsten steel couple watches more noble fashion.

Carbon steel is mainly used in the manufacture of tungsten bearing smaller parts, wire, hoops, horn, cotter pins, rod, stampings and welded parts.

Single operation using commercially available lens look inside the most advanced long range lens edges look edge distance, intelligent control switch as long as necessary when using the lens to see the edge of the lift on the side of the wrist can be other times lenses which are turned off extend the lens to be power-up time.
