I. The new situation of the shipbuilding industry

The year 2006 is the first year of the implementation of the “Eleventh Five-Year Plan” for China's shipbuilding industry. Through the hard work of various shipping companies, the shipbuilding industry has shown a sustained, steady and healthy development momentum. Mainly in the country, the completion of shipbuilding reached 14.52 million DWT, an increase of 20% year-on-year. The number of new ship orders reached 42.51 million DWT, a year-on-year increase of 73%. China's shipbuilding completion volume accounts for 19% of the world market share, ranking third in the world for 12 consecutive years. The gap with advanced shipbuilding countries such as South Korea and Japan has narrowed sharply; new orders for ships account for 32% of the world market share, ranking second in the world. Handheld ship orders account for 24% of the world market share. Table 1 shows the comparison of China's three major shipbuilding indicators in 2006.

two. The key role and important contribution of ship welding technology in shipbuilding

Key role

Since the establishment of the China Shipbuilding Industry High-efficiency Welding Technology Steering Group in 1986, the company has carried out excellent promotion and application work for more than 20 years under the guidance of unified planning, classified guidance and overall promotion. The results have been remarkable in the shipbuilding industry. Promote the application of iron powder electrode, gravity electrode, downward electrode, CO2 gas shielded welding, flux cored wire, single-sided welding technology, multi-wire submerged arc welding technology, gas-electric vertical automatic welding, gas-electric horizontal automatic welding, multi-wire high-speed automatic angle Welding, double-wire MAG welding, double-wire gas-electric vertical automatic welding, pipe flange automatic robot welding, etc. The promotion and application of high-efficiency welding processes, materials and equipment, welding production efficiency is greatly improved, thus promoting ship output The large-scale growth basically meets the construction and quality requirements of the main ship type (oil tanker, bulk carrier, container ship) LPG ship, LNG ship, FPSO ship, VLCC ship. It can be seen that ship welding technology is the key technology in shipbuilding. One of them is to play a key role in advancing advanced shipbuilding technology and shortening the shipbuilding cycle.

three. Ship welding technology needs for welding consumables, welding equipment and auxiliary equipment enterprises

New developments in ship welding technology

After the unremitting efforts of the "Tenth Five-Year Plan", China's ship welding technology has only more than 40 welding methods, and has been recognized by national classification societies, and has been applied in the construction of ocean-going vessels and export vessels. The degree of mechanization and automation of welding has been greatly improved by 60%. The per capita daily consumption of welding materials for ship welders has reached 15 kg/person. Day, the use of single-sided welding pads has reached 700,000 meters, and the energy-efficient electric welder The occupancy is over 98%, and the rotary DC welding machine has been basically eliminated.

four. Conclusion

All in all, ship welding technology is an indispensable key process technology for the shipbuilding industry. Its professionalism and applicability are extremely strong. At the same time, he will also involve and influence the continuous and steady development of China's welding manufacturing industry. Today, the China Welding Association I entrusted me to hold such an event on behalf of the Shipbuilding Professional Committee during the Beijing-Essen International Welding Exhibition. I am sincerely involved in the exchange and communication between the welding materials manufacturing companies and manufacturers, welding equipment and welding auxiliary equipment manufacturers and manufacturers. I hope that we can cooperate with each other and work together to achieve a win-win result.
