Our materials engineers and metallurgists provide independent expert opinions regarding weld or material failure analysis. Forensic investigation of your product failure is accomplished by analyzing and testing materials and welds. Root cause analysis of your weld or material failure can be identified by our failure analysis experts. Features of our product failure analysis capabilities include:

Weld failure analysis Analysis conducted by registered professional engineers Failure mode identification Broad failure analysis experience Fracture evaluations Root cause analysis determination Photographic documentation

EXPERIENCE

Our staff has had broad industrial experience. Examples of industries in which our staff has had welding, manufacturing or failure investigation experience:

• Aircraft / Aerospace	• Gas turbine engine components
• Weldments.	• Petrochemical / Pharmaceutical plants
• Offshore structures	• Industrial machinery
• Heat exchangers	• Food processing equipment
• Ships	• Oil and gas transmission pipelines

LITIGATION INVESTIGATION AND EXPERT WITNESS

Our services can assist defendant/plaintiff from the initial legal proceedings through trial. We provide support in the following areas:

• On site accident investigation

• Product liability

• Technical advisors to counsel

• Conformance to industry specifications

• Evaluations conducted by registered professional engineers

• Failure mode and root cause identification

• Forensic Macro/Microphotographic documentation

• Industrial and consumer product failure analysis

If your company is experiencing these or other welding problems you can engage AMC to solve your welding or failure issues. Hire AMC to act as your weld failure analyst.

Gas Metal Arc Welding (GMAW) is frequently referred to as MIG welding. MIG welding is a commonly used high deposition rate welding process. Wire is continuously fed from a spool. MIG welding is therefore referred to as a semiautomatic welding process.
MIG Welding Benefits

• All position capability
• Higher deposition rates than SMAW
• Less operator skill required
• Long welds can be made without starts and stops
• Minimal post weld cleaning is required

MIG Welding Shielding Gas

The shielding gas, forms the arc plasma, stabilizes the arc on the metal being welded, shields the arc and molten weld pool, and allows smooth transfer of metal from the weld wire to the molten weld pool. There are three primary metal transfer modes:

• Spray transfer (MP3 Audio)
• Globular transfer (MP3 Audio)
• Short circuiting transfer (MP3 Audio)

The primary shielding gasses used are:

• Argon
• Argon - 1 to 5% Oxygen
• Argon - 3 to 25% CO₂
• Argon/Helium

CO₂ is also used in its pure form in some MIG welding processes. However, in some applications the presence of CO₂ in the shielding gas may adversely affect the mechanical properties of the weld.

Common MIG Welding Concerns

We can help optimize your MIG welding process variables. Evaluate your current welding parameters and techniques. Help eliminate common welding problems and discontinuities such as those listed below:

Weld Discontinuities

• Undercutting
• Excessive melt-through
• Incomplete fusion
• Incomplete joint penetration
• Porosity
• Weld metal cracks
• Heat affected zone cracks

MIG Welding Problems

• Heavily oxidized weld deposit
• Irregular wire feed
• Burnback
• Porosity
• Unstable arc
• Difficult arc starting
