[MW:16580] Linier indications observed in Radiography Testing in SA240 310S weld

Dear Expert,

We are doing SA240 Type 310s material welding with WPS(GTAW) but there are lot of defects of linier indications(micro cracks) observed in Radiography testing.

We are using D&H make ER-310 filler wire for welding. We also preheat the joint up to 80 °C to avoid sudden cooling.

Can you guide me how to avoid linier indications(micro crack) in welding.

 

Regards,

Mukesh
