Welding auxiliary equipment and apparatus

In recent years, we have seen the rapid development of science and technology in our great motherland. This made me feel extremely proud for me as a Chinese. With the advancement of technology and the progress of people, we will join the Chinese cutting machine trading network to make progress together. Join the hotline, we look forward to your call.

Welding auxiliary equipment should be welding process equipment. It covers a wide range, including bevel processing equipment, welding assembly fixtures, welding positioner, welding operation machine, post-treatment equipment for welding parts, special welding equipment, and robot workstations. And welding production lines. There are 24 welding equipment manufacturers in China and more than 10 have annual output of more than 20 million yuan. Some companies have developed at a faster rate and have already had larger scales. Some welding equipment has achieved mass production. Such as Wuxi Yangtong Machinery Equipment Co., Ltd., the total sales in 2001 reached 120 million.
At present, China has been able to produce 8m×10m heavy-duty column beam type manipulators, and the maximum tonnage of heavy-duty welding roller frame reaches 400T. The automatic flood prevention roller carriage has been successfully developed and put into operation for many years, and the flood prevention accuracy is ±1.5 mm. Welding positioners have been serialized with a maximum load capacity of 100T.
The production of domestic welding accessory equipment has formed a certain scale, and the product quality has approached the international level. There are 34 professional production companies producing wire feeders, various welding guns and various types of gun accessories, welding clamps, contact nozzles, pressure reducers, flow meters, welding masks, welding rod drying equipment, and ceramic nozzles. The annual output value exceeds 100 million yuan. Among them, Guangzhou Abitek Welding Technology Co., Ltd. has formed a group company with a number of domestic welding torch manufacturers. The production scale is very large. In 2001, the total output of welding torches has reached 90 million yuan.
The problems are:
(1) The development of new products is small, and there are few varieties. Most of them are in the state of mutual imitation.
(2) Some similar products with low technological content are in low-level, low-price competition, which causes enterprises to fall into a state of extremely low profits and it is difficult to develop themselves.
(3) There are fewer companies that have strong comprehensive strength and can play an active role in promoting industry development and self-discipline in the industry.
(4) The overall coordination ability of the industry is poor.

Our Quick Release are used for pipe connection,especially for the Dredging pipe.

Dredge pipe pieces are a variety of pipes on board of dredgers like bend pipe, T-pipe, pitched T-pipe, Y-pipe, cross pipe, strait pipe, and conical pipe.


These dredge pipe pieces are used on-board of dredgers to connect the Dredge Pump with the discharge pipe.

Mostly the pipes are made from cast steel. Sometime Welded Pipes are used.


Dredge pipe pieces may have different thicknesses, shapes and lengths, they are also provided with lifting lugs for easy handling. They supposed to have smooth surface for low frictions. In most cases the flanges are cast together with the pipe to provide a stronger connection between flange and pipe.


It is also very important that the entire dredge pipe pieces to follow the shape of the flow resulting in low frictions and to avoid vortexes.

The materials used to manufacture the dredge pipe pieces are both manganese alloy that provides high elongation and impact value or high chromium, nickel and molybdenum alloy that gives high yield, high tensile and very high hardness values.
