Insufficient penetration depth during argon arc welding of stainless steel plates can result in poor weld penetration. This leads to a reduction in the thickness of the joint cross-section and becomes a source of stress concentration, ultimately resulting in incomplete weld penetration.

Causes of incomplete penetration during welding may include: 

1. Insufficient welding current:  If the welding current is insufficient, the arc may not be strong enough to fully melt the welding material, resulting in incomplete penetration of the weld. 

2. Excessive welding speed: Welding too quickly can prevent the welding arc from adequately melting the welding material within the required time, leading to incomplete penetration of the weld. 

3. Inadequate welding area: If the welding area is insufficient, particularly at the edges of the weld joint, complete melting of the welding material may not occur, resulting in incomplete penetration of the weld. 

4. Poor welding environment: Factors such as gas interference or unfavorable welding conditions, such as inadequate argon flow or exposure to strong winds, can also affect the weld penetration. 

5 . Inadequate welding technique: Lack of sufficient welding technique or experience, such as improper welding angles, techniques, or misalignment of base materials, may also contribute to incomplete weld penetration. 

Addressing these issues may involve adjusting welding parameters, improving welding techniques, ensuring proper welding environment conditions, and using appropriate welding equipment and materials.
