I have some problems at understanding the provision of AWS D1.5-96 Section 9.14(page 132). Any help to describe the section in more detail is appreciated. The section is quoted as:

"9.14 Connections or Splices in Compression Members with Milled Joints
If members subject only to compression are spliced and full-milled bearing is provided, the splice material and its welding shall be arranged, unless otherwise stipulated by the applicable general specifications, to hold all parts in alignment and shall be proportioned to carry 50% of the computed stress in the member. Where such members are in full-milled bearing on base plates, there shall be sufficient welding to hold all parts securely in place."
