The results of the calibration of the residual stress distribution diagram in Figure 2 show that the farther away from the weld center, the smaller the residual stress. The reasonable design of the welding seam structure of the pneumatic ball valve body can effectively reduce the residual stress caused by the deformation of the valve body after welding. At the same time, different auxiliary methods such as vibration and air cooling can reduce the residual stress after welding to varying degrees. In general, vibration welding can effectively release residual stress after welding. After welding, X-ray flaw detection and ultrasonic flaw detection are completely qualified; Mechanical property evaluation, tensile test, impact test and side bending test are qualified; The weld heat affected zone is qualified according to JB4708.

To do a good job in the next step of pneumatic butterfly valve sales, Tongfeng pneumatic butterfly valve should further improve its market strategy, focus on customers, continue to strengthen the advantages of pneumatic butterfly valve business competition as the starting point, take satisfying demand, guiding demand and creating demand as the permanent pursuit, give full play to the advantages of integration of production, marketing and research, and vigorously launch high-end products, Efforts should be made to cultivate the world competitiveness of the commodity chain, coordinate the two shopping malls at home and abroad, accelerate the improvement of the implementation network, use the implementation strategy sensitively, strive to improve the brand image, expand the share of domestic shopping malls from time to time, actively expand overseas shopping malls, and promote the continued and useful development of pneumatic butterfly valve business.
First, firmly establish the concept of customer first. We should further change our concept, unify our thinking, fully understand that selling operations is a "life project" that the company continues to carry out, and really strengthen our initiative to cope with the fierce market competition together. In the operation, we should provide customers with high-quality goods and services, and provide technical services before, during and especially after sales; To create higher value for customers, we should try our best to create market demand together with fully satisfying the market demand. At the same time, we should accelerate the innovation of system and mechanism and business process reengineering based on the market orientation. We should do our best to do everything that fits the market orientation, and we should not obscure the change of anything that does not fit the market orientation.
Second, we should fully implement the strategy of expanding shopping malls. On the basis of deepening shopping malls and users, all kinds of goods will be investigated and dissected, and we will contact our own production and R&D status, discuss and draw up detailed plans and implementation plans for all kinds of goods. We should speed up the development of new commodities, take shopping malls as the guide, organize in a unified way, and avoid going it alone and repeatedly developing; We should pay attention to the development and production of high-end products that have been introduced, vigorously promote strategic cooperation with major customers, and accelerate the development of new products. We should try our best to do big processing and import business.
Third, we should accelerate the improvement of the production, marketing and research liaison mechanism. It is necessary to strengthen the connection between production and marketing, adhere to the market orientation, adhere to the principle of "sales based production, production based supply, and production based promotion", adjust the production operation plan, and truly complete the "front call and back call" of sales and production. It is necessary to strengthen technical support, accelerate the establishment of the technical service system required by the custom stores, strictly implement the service handling methods for pneumatic butterfly valve commodity users, and work together to develop customer oriented technical services. It is necessary to clarify the obligation positioning between the pneumatic butterfly valve business division and the pneumatic butterfly valve sales system at all levels, improve the principles, rationalize the process, strengthen internal management together, pay attention to the "three basics" operation, and strive to complete fine management, standardized management and strict management.
Fourth, we should vigorously promote network construction. It is necessary to distinguish different kinds of goods, grasp and improve the outlet scheme and plan, accelerate the construction of outlets, and enrich the customer managers and other sellers to the front line of outlets as soon as possible; It is necessary to comprehensively consider production, sales, cost and other factors, and make overall plans to improve the production of pneumatic butterfly valves, the construction of storage equipment for selling companies and key points directly supplied to users, so as to create conditions for optimizing logistics from time to time. We should focus on improving the logistics distribution management and inspection methods, further improve the commodity distribution rate, and enhance the training and inspection of logistics service providers together to ensure the safety of logistics transportation.
Fifth, we should strive to cultivate high-quality talent troops. Accelerate the improvement of the incentive mechanism, establish and improve the position sequence of all kinds of talents and the salary distribution principle of their habits; Accelerate the optimization of the structure of the selling force, contact and promote the network construction, and improve the share of front-line personnel sold by pneumatic butterfly valves; Efforts should be made to strengthen the training of the betrayed troops, and the key points should be to improve the selling of know-how and exchange and reconciliation skills; Strengthen the education of honest employment, vigorously promote the openness of affairs, and strengthen the discipline of principles, so that the sellers will not, cannot, and dare not corrupt.
Cultivating a strong brand is a question that stainless steel hose companies need to deal with
