ปัญหาการเชื่อมแผ่นสแตนเลสทั่วไป (1)
กระบวนการเชื่อมแผ่นเหล็กสแตนเลสเป็นขั้นตอนสำคัญสำหรับการผลิตอุปกรณ์สแตนเลส SUN-YEE TECH สรุปปัญหาการเชื่อมทั่วไปสำหรับการอ้างอิงของคุณ.
คำถาม 1: 6mm 316L stainless steel plate welding with what welding method
คำตอบ: คุณสามารถใช้การเชื่อมทิกแบบแมนนวลได้ (เอ็มทีจี), วิธีการเชื่อม CO2, การเชื่อมแบบแมนนวลสามารถทำได้.
การเชื่อมอาร์กอนแบบแมนนวล: การเลือกลวด ER316L, 2.5 thick or 3.2 thick can be. For 6mm thick plate can be used X-bevel. Splicing welding should pay attention to the welding deformation problem. Can be front and back are welded once, try to offset the impact of welding deformation.
วิธีการเชื่อม CO2: If you want to get better results, you can use flux-cored wire (E316LT) for welding. The reason for choosing flux cored is that the spatter is extremely small and the weld protection effect is good, but it is more expensive. Operation, pay attention to the operation of interlayer root clearing, must remove the flux skin before the next welding.
Manual electrode welding: manual electrode welding can also be used to deal with. Select A207 welding rod for welding. Stick welding also requires the operation of interlayer root cleaning.
คำถาม 2: Thin plate with argon arc welding welding skills
คำตอบ: It depends on the specific requirements. Weld seam flatness, the size of the deformation, whether it needs to be polished, ฯลฯ. 0.7mm thickness above the thin plate can be welded.
In general, 0.7mm plate welded well will have a certain deformation. In order to reduce the degree of deformation can be tried according to the following steps:
- try to reduce the gap between the weldments (the tighter the better);
- If you want to fill the wire, the wire must be fine, 0.8 can be; 3.
- The current should be a little small, small enough to dissolve the wire on the line, about 30A or so, the welder is different, according to the welder depending on the welding machine;
- The welding speed must be fast, the faster the better, the deformation is also the smaller, the more beautiful the weld. Weld is also the more beautiful, if there is water cooling is better;
- The welder also have to pay attention to the general use of inverter AC and DC welder, the current is more stable. This kind of welding machine will be a little more expensive.
- Hire skilled operation, professionalism and strong technical staff.
