MTI WELDERS HAVE EXPERIENCE WITH VIRTUALLY EVERY MAJOR BRAND

Weld engineering is always available to MTI customers. Our staff of highly trained welders and supervisors work with customers to review job plans and processes. MTI welders are highly trained in both manual and orbital welding and meet all ASME Sec IX criteria. MTI maintains ASME Certificates of Authorization including: ‘PP’, ‘U’, ‘S’, and ‘R’ Stamps.

No matter what materials are at issue (i.e. stainless, carbon steel, inconnel, chrome; P11, P22, P91) strict adherence to MTI Safety, Welding and Quality Manuals is maintained which assures that customer projects are completed on time in a safe and professional manner.

Narrow Groove / Orbital

MTI POWER is expert in automatic, orbital welding. We Like The Dragon Weld Head.

Heavy wall, narrow groove welding; when it comes to  jobs with lots of critical welds nothing can stack up to narrow groove’s efficiencies – the same quality and speed, day and night, no matter how difficult the access or how unfriendly the environment.

Manual Welding

Our welders and supervisors work with customers to review job plans and implement the welding technique that will work best. If the job calls for manual welding, our staff has the experience necessary to meet all ASME sec. IX criteria. We maintain ASME Certificates of Authorization (“PP”, “U”, “S”, “R” Stamps).

MTI maintains strict adherence to its Safety, Welding and Quality Manuals to assure that projects are completed on time and in a safe, professional manner.

MTI Welders are trained at the MTI Mock up, Training and Certification Facility in Marseilles, IL. MTI welders have experience with virtually every type of welding process

Large OD Pipe & Vessels

MTI has vast experience in large OD pipe welding. Whatever the appropriate welding technique, MTI welders are tested and certified – they’ll get you through your project to its completion – on time and on budget.

MTI welders are highly trained in both manual and orbital welding. Our welders have experience with large OD pipe and vessels, and meet all ASME Sec IX criteria. MTI maintains ASME Certificates of Authorization including: ‘PP’, ‘U’, ‘S’, and ‘R’ Stamps.

 

Exotic Metals

MTI has considerable experience in the welding of exotic materials; Stainless and duplex (ferritic, austentitic, precipitation hardened), high-nickel alloys , Chrome (P11, P22 and P91), Inconels and Hastelloy.

 

Weld Engineering

MTI POWER’s team of welding techs and engineers is there to work with customers to review job plans and make sure that the job is completed on time and in a safe and professional manner. MTI Staff will be there to:

Qualify and write welding procedures to meet all appropriate ASME Codes.

Review for  compliance with applicable  codes (ASME, AWS, API)

Maintain ASME Certificates of Authorization for  Power Piping and Pressure vessel work (“PP”, “U”, “S”, “R” Stamps).

Consult  regarding weld joint configurations – (narrow groove, standard groove, J-preps , consumable inserts etc.)

Choose the proper processes:  ORBITAL MACHINE or MANUAL – Gas Tungsten Arc Welding (GTAW), Shielded Metal Arc Welding (SMAW),

Gas Metal Arc Welding (GMAW) Flux Core Arc Welding (FCAW),  Autogenous Welding (GTAW Fusion)

Consult on base metal heat treating  (ASME code compliance)

Order/purchase code materials and weld filler per ASME  Sec. II (or applicable)

Work with Authorized Inspectors and Authorized Nuclear Inspectors for required code work

Publish Work Travelers

Maintain strict adherence to Safety, Welding and Quality Manuals

Labor Support / Training

MTI offers the most qualified machining and welding personnel in the business and claims a 100% customer satisfaction record in field service projects.

MTI Power has tested and certified over 200 welders. Our reputation in the business is one that few can match; the best trained welders, project managers, supervisors and technicians in the business.

 

Special Projects

Cracking on Turbine Inlet Sleeves – MTI has developed fast and accurate methodology for repair of these difficult to access nozzle/sleeve fixtures. MTI Machines were specially designed to quick mount while still maintaining the ability to fine adjust for critically accurate cutting/machining. Depending on the situation, ID Machines can be used.  Material is often P91, and the welding repair on these units is critical. Indicators are mounted, and a  special welding technique is employed to accommodate movement insuring that the final welds are square and straight.

Steam Chest Replacement –  MTI worked with the customer to support them at their fabrication shop and on-site during the install.  The fabrication stage of the project was  done manual ly (4″ – 5″ wall ), welding each side of the steam chest to the stop valve. The install stage involved heavy wall, narrow groove welding of the Throttle/Control valves (2¼ chrome/1-moly). All of these welds were shot and passed inspection.

Ball Valve Surfaces degrading and flaking – MTI worked with the customer’s material engineers and the valve manufacturer to overlay stainless surfaces with several layers of alloys including Stellite.

Hot Reheat – pipe replacement project. The pipe material was P-22 (2¼
