With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
With guidance from some of the best in the industry, students will master the four most popular types of procedures: Shielded Metal Arc Welding (SMAW) With this particular type of welding, the welder follows a manual process of stick welding. The stick uses an electric current to form an electric arc between the stick and the metals to be joined.
The best way for a welder to know how to weld a particular steel or steel classification is through the use of a Welding Procedure Specification (WPS). A WPS is a written set of instructions (specifications) detailing the welding procedure, joint preparation, filler metal, current type and range as well as any required preheat, interpass temperature controls and postheat treatments.
TWI's welding engineers support TWI's Industrial Members in developing welding procedures and preparing welding procedures specifications (WPS) or reviewing existing ones according to the major welding standards, such as ASME IX, EN ISO 15609-1, AWS D1.1, Civil Aviation Authority (CAA) procedures.
How to write a welding procedure specification (ISO 15614-1) One of the most important documents in regards to welding is the WPS (Welding Procedure Specification) and many people working with WPS look at them like they are just an issue, or something that only the engineers and quality control technicians have to worry about, but is it a hard thing to create and/or look at?
Standard Welding Procedure Specifications (SWPS) All SWPSs are supported by Procedure Qualification Records (PQRs) which meet the rules of AWS B2.1 and which in addition are intended to meet the rules of the major codes which govern the intended applications such as AWS Structural Codes (D1.1, D1.2, D1.3, etc.),best q195 welding procedure
in the Welding Procedure Specification. When higher preheat is required by the applicable construction code (i.e. B31.1, B31.9, etc.), that preheat shall be used for production welding. Welding on metal that is wet is strictly prohibited; wet metal shall be heated until it is at least warm to the touch to assure removal of moisture.
Welding Procedure Specification Example A WPS is a document that describes how welding is to be carried out in production. They are recommended for all welding operations and many application codes and standards make them mandatory
The manufacturer initially drafts a preliminary welding procedure (pWPS) which is used by one of the manufacturer's competent welders to prove that it is capable of producing a welded joint to the specified levels of weld quality and mechanical properties. The welding procedure approval record (WPAR) is a record of this weld.
The purpose of the Welding Handbook for maritime welders is to provide guidance in modern welding and related processes and to provide the welder with a source of practical information on the right solution to specific onboard welding problems. Experience gained from user contact and welding training of crewmembers showed that

Each of the WPS America.com prequalified welding procedure specification has practical weld parameters, right shielding gases for spray, short circuit or globular mode of transfers, with helpful notes, technique or code's rules, based on the latest edition of AWS codes. It has been prepared by professionals and code experts in weld industry; it includes welding of steels and stainless steels (Plate, Pipe, Sheet, Box).
A Welding Procedure Specification (WPS) is the formal written document describing welding procedures, which provides direction to the welder or welding operators for making sound and quality production welds as per the code requirements .
ally free of slag entrapment and porosity. These welds are best able to meet strict radiographic requirements for high pressure, high tem-perature or low temperature piping. Because of the low hydrogen deposit, these electrodes have an advantage for high strength pipes susceptible to hydrogen cracking.-4-CROSS COUNTRY PIPELINE Vertical Down Welding

welding characteristics of stainless steels, so they may exercise better control over the finished products with respect to welding. In addition to welding, other ancillary joining methods are discussed, including soldering and brazing.
When this high carbon material is allowed to cool slowly, crack free castings can be made. Remembering this is helpful when welding cast iron: during and after welding, the casting must either be allowed to cool slowly, or should be kept cool enough that the rate of cooling is not important.
Hey guys, a lot of you have asked my what machine I would suggest for anyone starting out or wanting to get into pipeline welding. I always suggest a Lincoln SA 200 and her is why. Best way to best q195 welding procedure

Welding Procedure Qualification Steps As a summary, welding inspector may be involved with each of the following steps or only a few depend on the structure of the particular organisation Select welding variables Check equipment and materials for suitability Monitor weld joint fit up as well as actual welding,
The Procedure Handbook for Arc Welding groups A514 and A517 under the same category (Category D) and recommends the exact same processes and procedures. T-1 Steels (ASTM A514) have good weldability, but care must be taken when selecting the right process and welding procedure.

When welding low alloy 1 1/4 Cr 1/2 Mo and 2 1/4 Cr 1 Mo with up to 0.05% max carbon, typically 8018-B2L / 9018-B3L (L = low carbon) can be used. When welding higher strength alloys or when tempering and quenching are required to attain the higher strengths the higher carbon 8018 B2 and 9018 B3 electrodes are utilized.
The new NCPWB Welding Procedure Specification numbering system clearly defines the type of metals to be welded, the welding process used and allows for identification of variations in a process. This numbering system will be used on all Welding Procedure Specifications revised or developed in the future.
