1. Inspection of the appearance and shape of the main body and fillet welds.
2. Whether the weld surface defect splash edge has been eliminated.
3. Whether the weld is inspected according to the requirements of the drawings, and the quality level and inspection ratio meet the requirements of the drawings.
4. Weld welding records, including actual welding process parameters, welding material warranty number, weld number and welder number.
5. Internal quality inspection of welds (1) Before the heat treatment or hydrostatic test of the container, the inspectors shall examine the X-ray film one by one, and require the manufacturer to provide ultrasonic magnetic powder or stain detection report, after confirming that the internal quality of the weld is qualified. Agree to the manufacturer to heat treatment or hydrostatic test of the container (2) After the heat treatment or water pressure, the ultrasonic magnetic powder or coloring inspection is required. When the customer requests it, the inspector should be present to witness the above inspection.
6Whether the weld is subjected to the heat treatment heat treatment required by the pattern, whether the welding test plate is carried out together with the equipment.
7 Whether the performance of the welding test board meets the standard requirements.
8 welder stamp: The main weld of the container should be stamped with the welder code on the specified part. When it is forbidden to weld the welder, such as low temperature container, it is necessary to do the drawing and record the four heat treatment process and curve review.
Beryllium Copper
One of the highest strength copper based alloys available on the market today is beryllium copper, also known as spring copper or beryllium bronze. The commercial grades of beryllium copper contain 0.4 to 2.0 percent beryllium. The small ratio of beryllium to copper creates a family of high copper alloys with strength as high as alloy steel. The first of the two families, C17200 and C17300, includes high strength with moderate conductivity, while the second family, C17500 and C17510, offers high conductivity with moderate strength. The principle characteristics of these alloys are their excellent response to precipitation-hardening treatments, excellent thermal conductivity, and resistance to stress relaxation.
