Sounds like the interviews went well
I would tell them what experience you do have with welding... Let them know what other factors you can contribute to their company. Tell them you are a hard worker, you are organized, on time, meticulous, etc.. Any extra skills that you can bring to the table.. like book keeping, or clear driving record, or computer skills (obviously you have), teaching or traing you have doen in the past, ANYthing and everything why you can add to their company to make it 'more complete' and better to have you work for them.. You kinda have to sell yourself even if you don't technically fit the position you read what they are looking for and you craft what you are going to say as to what you can provide and why you can provide it better then anyone else they may have in mind to hire.... Etc...
Interviews go much better if you sit down and figure out what they want, answer everything they want in an ad, figure out how to negotiate salary, benefits, sign on bonus, gas for traveling, etc... You just have to play the game. I have never been turned away in a interview. You have to go in with confidence and a firm handshake and let them know you are the person they have been dreaming about.... I mean half the time once you get gired you won't be doing exactly what they say anyway, and they'll have to give you some sort of OJT... Don't let them no you are desperate for a job either. Always leave without accepting the offer but let them know you will get back to them with 24-48 hours with an answer that you need to talk it over with your husband. That's how you get salary increases. They will always low-ball you, but if you have done your homework as to what the cost of living is in the area, and what the going rate for a job in taht area is, then when you call them back you can say " I appreciate the offer and your time and after further discussing the position with my husband and paying for day care, looking at the average pay rates and statistics in the area (list the websites for them where you did your search) we feel that X may be a more suitabe salary." Then you can also say stuff if they are unwilling to budge to have a 3 month review so you can get a raise.. rather then waiting a year.
Ohh and always have a nice little paragraph memorized because this is my favorite questions they always ask:
Tell me about a time when a tough decision arose and how you handled it?
Tell me about a time in which you were recognized by a past employer?
Good luck
