How is a double girder crane welded?

For large double girder cranes, the success of the weld depends primarily on the correct guidance. Let us judge how the double girder crane is welded. There are many aspects to see.

The welding process factors affecting the tensile strength and bending properties of the welded joint include the welding method, the type of base metal, the number of welding electrodes, and the type of shielding gas. If these factors change, the entire portal double girder crane will have to re-evaluate the welding process.

Don't underestimate some secondary factors, don't change some secondary factors to re-evaluate, and say that secondary factors are not important. If welding is performed by two or more welding methods on a double girder crane, each welding process or each welding process should be evaluated. Of course, a combined assessment is also possible.

As demand has decreased and production capacity has increased, the inventory of construction machinery products on the market is increasing.

After a major change in the past two years, the brilliant victory of construction machinery has ceased to exist. Industry companies have begun to consider more questions about the aftermarket. Construction machinery enterprises shall comply with the post-development market business, improve the corporate profit model, and make the post-marketing profits cover the funds required for the operation of the enterprise as much as possible, and gradually alleviate the pain caused by the fluctuation of the enterprise. Industrial market.

Faced with the difficulties of market, capital, efficiency, development, etc., the business decision of Shuangliang Crane has begun to undergo major changes. Enterprises in the construction machinery industry actively adjust their business strategies according to their own characteristics. The core of pursuing scale expansion is to focus on the pursuit of operational quality. Pursuing profitability and profitability, do not blindly pursue scale, seats and market share; effective measures to strictly control business risks, strengthen product cost control, strengthen capital and budget management, and promote stable and improved business indicators.
