Certifications for Commercial Welders and Industrial Welding Parts Suppliers

یازار:‌

Both commercial welders and industrial Welding Parts Suppliers (XINGHUI) are entitled to get the so called welder certification or welder qualification. When the commercial welder has such a document, this means that this welder is capable of creating welds under specific welding procedure that are of excellent quality.

The certification of the commercial welder is based on certain special tests that determine one’s skill and ability to provide a sound weld metal. The welder tests can be different and can be quite specific depending on the type of the metal, type of the material (if not metal), joint design, thickness, as well as welding process including arc welding, mig welding, tig welding, etc. In general, the test is done in accordance to the particular code and are usually administrated by the American Welding Society and the American Society of Mechanical Engineers. The commercial welding equipment of some manufacturers also can come with its own standards.

As a rule in the United States, the qualification of the welders is done according to the American Society of Mechanical Engineers and the American Welding Society. However, some states and many countries use own qualifications for the welders. When the commercial welder passes a test, the employer gives a certificate stating the ability of the worker to weld and the extent to which one is qualified to do the job. When the document expires, the welder must be tested again.

The Significantly Affect the Cost of Stamping Parts

یازار:‌

Long-run or conventional Stamping Parts (XINGHUI) is done using simple dies, compound dies, progressive dies, and transfer dies. One purpose of this chapter is to present a systematic approach for identifying, at the configuration design stage, those features of the part that significantly affect the cost of Stamping Parts. The goal is to learn how to design so as to minimize difficult-to-stamp features.

We will also discuss a methodology for estimating the relative tooling cost of proposed stamped parts based on configuration information and on the assumption that progressive dies are used. Unlike injection molding and die casting, however, where the total relative tooling cost can be determined at the configuration stage of design, in stamping only the maximum and minimum relative tooling cost can be determined. The reason is that some of the details required to finalize the relative tooling cost can only be determined after parametric design. For example, in injection molding and die casting, any hole that is not parallel to the direction of mold closure is an undercut. In stamping, on the other hand, whether or not such a hole is an undercut depends, not just on the presence of the feature, but also on its dimensions and tolerances. Nevertheless, a great deal of information concerning tooling cost can be determined at the configuration stage, and this information can and should be used to help guide the generation and selection of part configurations before parametric design is done.

Processing and Material Behaviour of Plastic Injection Parts

0 گؤروش
یازار:‌

The injection Plastic Injection Parts (XINGHUI) there is a distinct lack of understanding surrounding the effects of processing on material behaviour. The fundamental behaviour of thermoplastics is commonly overlooked due to this lack of knowledge. Simply passing the manufacturing of a component over to a moulder can be a recipe for disaster. In some cases corners are cut to increase profitability, other times the moulder may be inexperienced with the material and not have the required equipment. However, with some basic knowledge and independent assistance a more robust product can be manufactured.

Drying of granules prior to moulding often seems unnecessary, but excess moisture will create steam within the melt leading to voids or silver streaking. For some polymers the effects of moisture during moulding is far more serious as hydrolytic degradation occurs, resulting in a brittle moulding. In the case of hydrolytically sensitive polymers the drying regime recommended by material suppliers should be adhered to e.g. using desiccant or vacuum driers.
