    Presented at ICALEO 2010

    Thick plates with different gauges have increased their use in various industries such as the shipyard and offshore industries. The arc welding techniques are the common ways to join the thick plates, which usually requires multipass and interlayer control. In addition, high heat input during arc welding also leads to the large distortion in the weld. Indus...

    Presented at ICALEO 2010

    The use of high-strength galvanized steels has significantly increased in different industries. However, welding of the galvanized steels in a gap-free lap joint configuration presents a difficulty in dealing with the highly-pressurized zinc vapor due to the lower boiling point of zinc than the melting point of stee...

    Purchasing the Ounce of Prevention: Vital Tools for Today's Industrial Laser Users
    Authors:
    John McCauley, Ophir-Spiricon, LLC; Logan UT USA
    Presented at ICALEO 2010

    An ounce of prevention is worth a pound of cure. Wise words to live by. But in these days it seems as if several are contemplating the cost of the ounce of prevention. Todays economical climate has most everyone in survival mode, giving careful consideration as to where to delegate monies. Companies are more careful these days to maximize the return on their investments than perhaps they have been in the past. For example, sometimes it just makes sense that new purchases are put on hold while the maintenance of existi...
