welded corners on sliding doors

I'm looking at replacing a 12' wide sliding glass door with 3 panels. The middle one slides, and the others are fixed. The door I'm looking at, by Sunrise, has welded corners on the sliding door are welded, but the corners on the fixed doors are not. The welded corners are very important to us on the sliding door because the 40+ year old door separated in one corner, and probably as a result the glass in the other bottom corner is cracked. (although the contractor said that this sometimes just happens with decades-old doors) I understand that another benefit of welded corners is preventing air and water infiltration. The contractor believes that welding corners are not available for the fixed panels of sliding glass doors. I wondered if anyone has any thoughts on this topic. Thank you.
