Status Quo and Development Trend of welding equipment

2016/5/19      view:
1. The size of the industry

About a third of steel products need to go through the welding process, except for a few high-end equipment, welding equipment of these basically provide their own, China has become the world's largest welding equipment producer and exporter.

At present, China welding machine industry in the enterprise's economic main types of private enterprises, joint-stock companies, joint ventures and wholly foreign-owned enterprises. The total number of enterprises is about 700, the annual output value of about 100 billion, of which more than 100 million yuan in annual output value of enterprises with more than twenty.

At present, China welding equipment industry capacity exceeds demand, although upstream resources and raw material prices are rising, but the average sales price of the whole industry is down interval, the average profit sector increasingly slim. Core competitiveness and advantages of scale enterprises so that those who do not have the ability to develop small businesses getting smaller and smaller living space, the number of enterprises will be reduced gradually.

2. The level of technology industry

(1) the rate of application of energy-efficient CO2 welder, submerged arc welding machine greatly improved.
(2) welding inverter has been formed to promote the universal tendency, especially CO2 inverter welder gained widespread application.
(3) the rapid development of automatic welding equipment, widely used in high-speed locomotives, construction machinery, steel, household appliances, automobile and other industries, have occupied the dominant position.
(4) a substantial increase in the number of welding robots, represented by welding automation equipment, is widely used.
(5) In the context of the financial crisis, the number and size of welding exports are a substantial increase in market share increased substantially in the low-end business in international markets.

3. The level of development of foreign and comparative analysis of the gap between domestic and international

(1) welding digital control digital control of welding, it has become the mainstream of imported welder. Full digital control technology greatly improves control precision welding machine, welding machine product consistency and reliability, but also greatly simplifies the control technology upgrade. The domestic welding power, still analog control technology-based, although some manufacturers have also introduced a fully digital welding power source, but mostly in simple instead of analog control level, all-digital control action was yet to come, leading to market approval It is not high.

(2) process control intelligent welding power mostly imported free or optional approach provides welding expert system that allows the operator to enter the welding material, thickness, groove forms, such as welding conditions can automatically generate welding process. While domestic manufacturers of welding power supply is still very limited in research and accumulate work welding process, it is difficult to provide mature and reliable welding technology support, leading to price products in addition to domestic and imported goods and there is no competitive advantage, most high-end market share is still imported welder occupy. It is missing and gaps in intelligence and welding services, welding equipment mostly of pure machinery and equipment, without the burdens of welding the user to solve the problem of welding responsibility.

(3) System Integration Network provides foreign welding equipment mostly fieldbus interface, rich and controllable parameters, welding process control easier, significantly increase the level of integration of foreign automated welding systems. The domestic automated welding systems in general relay switch control group level, various automation components pass welding very limited amount of information, it is difficult to implement complex coordinated control of the welding process.
