For more than a century, CanForge has strived to build quality forgings to withstand the toughest, most demanding applications. Our forging process is a mix of precision and skill, from selecting the right materials to applying the best techniques to create a flawless product.

While forging has low rejection rates, occasionally there can be defects that affect the overall integrity of the product. As part of our quality testing process, we inspect our forgings to identify any imperfections.    

Forging Defects

Unlike casted or welded products, forgings have an optimal grain flow for strength and durability. And while CanForge aims to create the highest quality products, no method is entirely free from error. Here are common forging defects and how we test for them:

• Laps and folds: If the metal is not heated to the correct temperature, it can lose its shape by collapsing or folding onto itself. Folds can also occur if the amount of material exceeds what is required for the component.
• Cold shuts: This can occur when the die itself is not properly designed and causes cracks in the corners of the forging.
• Improper grain flow: If the metal’s flow is incorrect, the grain structure will not adequately withstand the applied force for which it is to be used.
• Exterior cracking: This defect can happen when the temperature of the metal is too low and the forging has been overworked.
• Interior cracking: This type of cracking occurs when improper cooling techniques are used. If the metal is overheated during the quenching process, the internal stress state of the metal can increase and cause cracked sections. 
• Unfilled sections: If there is something trapped in the forging die, such as lubricant or air, the metal will not fill the die completely and leave gaps. 

CanForge’s Quality Testing Process

Our rigorous testing allows us to guarantee premium forgings for our clients. We offer two types of testing.

Non-destructive testing (NDT) is non-invasive testing that ensures each forging is clear of defects. This is a cost-effective approach because it does not damage the component.

We conduct non-destructive testing using these methods:

• X-Ray
• Magnetic Particle
• Ultrasonic
• Liquid Penetrant

We also offer destructive testing where we use a test piece or extra forging and apply controlled stresses until the forging is destroyed. This type of testing is useful for gathering more detailed information about how much impact the component can withstand. 

Our destructive testing methods include:

• Grain Size Testing
• Stress Rupture Testing 
• Tensile Testing
• Charpy Impact Testing
• Micro Examination
• Macro Examination
