Machine Shops & Welding Insurance FAQs
Does Commercial Property cover a CNC spindle crash or electrical board fry?
Standard property covers fire/hail; you need Equipment Breakdown (Boiler & Machinery) to cover mechanical/electrical breakdown of CNC machines.
What if we machine a customer's $40,000 titanium forging and ruin it?
Standard GL excludes property in your care, custody, or control; Bailees / Manufacturers Errors coverage protects customer-supplied stock.
Is mobile field welding rated the same as an indoor machine shop?
No—mobile/rig welding at jobsites or oilfield sites carries much higher fire/explosion exposure and must be rated separately.
Why do Texas oilfield and aerospace OEMs ask for Waiver of Subrogation on WC and GL?
So your carriers cannot sue the OEM if one of your machinists is injured while delivering or installing parts on their site.
